Spells you make are stronger than the ones you find and cast, so I would recommend doing research on your topic and making a chant just remember [it doesn't have to rhyme!] i suggest praying to Athena, the goddes of war and CRAFTS before starting your search on information or any god/goddess you feel closet to!

I'm not sure about telepathic invasion, but I've found that shielding visualizations help me keep away unwanted or invasive energies.
Try breathing in and out like you would if you were going to meditate. As you start to relax, visualize either white or pink energy coming out of your mouth as your breathe like your breath on a cold winter day. Imagine it surrounding you and slipping between you and the harmful energy, then expanding to push it away.
It may sound weird, but it's worked for me, and I'm very sensitive to energy. Send me a message if you want clarification on anything or have questions about anything else!

The best method in my opinion is a set of good personal shields. Learning to shield properly should be a basic skill of every magic user. Many of those new to magic don't realize that it's a good idea to create a personal shield that you use on a daily basis to prevent energy leakage from yourself or to avoid draining of your energy by another. It will also work to prevent others from accessing your thoughts or emotions. Here's some discussion about personal shields and a simple ritual.

"Creating A Personal Energy Shield

Each and every one of us has the ability to create personal energy shields. Since we are all energy, shields are simply an extension of ourselves. In the movie, Star Wars, we know energy as The Force. As narrated in the movie, The Force is a binding, metaphysical and ubiquitous power in the universe of the galaxy. Yoda points out that ?a Jedi?s strength flows from the Force? while training Luke Skywalker; Yoda also explains that ?you must feel the Force around you.?

The Star Wars movie has a lot to teach us about energy, if you haven?t realized. Here is an example. Being connected as One at source, we can get affected by the negative energies of another. This happens when we have a weak energetic boundary. We allow others to invade into our ?space? or field. An energetic boundary is an invisible shield that screens incoming and outgoing energy. It keeps our own energy field within a closed, safe and contained system. Holistic well-being arises when we have healthy, vibrant and luminous personal energy.

The first thing to know is that no one can invade our ?space? without our permission. Hence, a big part of energy leakage is caused by the failure on our part to take actions to protect ourselves. Oh yes, it is our personal responsibility. We cannot shift the entire blame to others if we leak energy. It is very important that we take steps for self-care and protection.

Signs of Energy Leakage

So, what are the signs of energy leakage? Signs can be one or more of the following: feeling persistently tired, a sense of chaotic energy, constantly ill, heaviness and migraines as a result of contact with others.

An empath or someone highly sensitive and compassionate can be like a ?sponge?. Empaths are prone to soaking up unwanted energy from others. They unconsciously absorb the feelings, difficulties or pain of others. When they do, they carry an extra load of negative energy that can affect their clarity.

The thing is to remain vigilant if this is the case for you. You need to learn how to shield yourself appropriately, even whilst you are sympathetic to the problems of another and wish to help.

Types of Energy Shields

There are many ways that you can create personal energy shields, such as visualizing that you are inside a cobalt-blue egg, circle of love, roses and so on. All variations are just as effective if and only if conscious intention is used to create one. Random thinking does not count. You won?t also want to create a weak and sloppy one with holes. The idea is to focus your mind and use your senses to experience the shield.

I share one variation that will be useful for Lei, since she needs to protect herself from toxic people.

Pink Rose Quartz and Mirrors Protection Shield

1. Be quiet for a while.

2. Release any stresses or tensions that you feel and relax.

3. Take in a few deep breaths.

4. Focus your mind on creating an energy shield using light from source.

5. For this shield, visualize and tangibly feel yourself surrounded by a wall of mirrors ? around, over and under. The mirrors face out. Hence, if there is negative energy that is directed towards you, it is reflected back outwards.

6. Your shield is completely sealed so that no external negative energy can enter.

7. At the same time, make the intention to allow only love to pass through both ways.

8. With you inside this shield, you may want to visualize yourself surrounded and embraced by the energy of pink rose quartz.

9. See, sense and feel the completeness of the shield for a few moments. Hold that in place with your intention.

10. For your future reference, make a mental note of how the shield feels like. This will make it easy for you to bring it back into existence whenever you need it. You will need to repeat steps 1-9 as the shield dissipates over time.

Extra tip #1. You can also call upon your spiritual team for extra protection from all people who are toxic and negative. Don?t be surprised when you receive evidence of their support.

Extra tip #2. Before you step out of your room in the mornings, make creating personal energy shields as part of your getting up ritual! If you perceive that there are any gaps, cracks or holes, just repair it with new mirrors.

Extra tips #3: The Mirrors Protection Shield is also excellent if you need to go into a crowded space. Protect yourself before entering a bus, train or shopping mall. "
